libx264 being noisy and ignoring loglevel #390

Closed IanButterworth closed 1 year ago

We shouldn't be seeing any of this because of https://github.com/JuliaIO/VideoIO.jl/blob/cac77da5451504eb0092717f6aae1804078d8ad8/src/VideoIO.jl#L127

For future reference, the problem was that https://github.com/JuliaIO/VideoIO.jl/blob/cac77da5451504eb0092717f6aae1804078d8ad8/src/VideoIO.jl#L127 is inside the __init__ function, but that's not run during precompilation of the package, so we have to silence also the precompilation block itself.
